Helmholtz's attempt to measure the speed of the nervous impulse in humans involved using the "reaction time" method, which measures the time it takes for a person to respond to a stimulus. This method became an important tool in the field of psychology, allowing researchers to measure the speed of mental processes. While Helmholtz's measurements were not as precise as later experiments, they did provide an estimate of the speed of the nervous impulse in humans.
